2 weeks of network coverage

We have had no coverage for 2 weeks now in our area Pimville, can't make calls, receive calls or use the internet. We've been calling Mtn and all weeks get time and time again is. "Something is wrong with ours network tower and they can't confirm when will it be fixed" Now find it very unfair to be paying for services that I cannot access. Can MTN please do the right right thing and let me go. Please cancel all my contracts with immediate effect and let me port to a different service provider. Cancel please with no costs as this your doing not mine.
